ARQHIE M. BAIRD, OF TQPEKA, KANSAS.

METALLIC. RAILROAD-TIE.

To all whom it may concern:

Be it known that I, ARCHIE M. BAIRD, a citizen of the United States, and a resident of Topeka, in the county. of Shawnee and State of Kansas, have invented a new and Improved Metallic Railroad-Tie, of which the following is a full, clear, and exact description.

The invention relates to metallic ties, such as shown and described in Letters Patent of the United States, No. 804,084, granted to me November 7, 1905. I

The object of the present invention is to provide a new and improved metallic railroad tie, arranged to securely hold the rails in place and to form an exceedingly strong and durable tie, comparatively light in weight.

The invention consists of novel features and parts and combinations of the same, .which will be more fully described hereinafter and then pointed out in the claims. r

Figure 1 is a perspective view of the improvement, and showing a rail in position; Fig. 2 is a transverse sec tion of the same on the line 2-2 of Fig. 1; Fig. 3 is a plan view of the same; 4 is a perspective view of one of the soft steel fastening lugs for the rails; Fig. 5 is out forms of fastening lugs 'for the rails; Fig. 6 is a plan view of the fastening lug shown in Fig. 5; Fig. .7 isa perspective view of a tie made of cast steel; Fig. 8 is a side elevation of a modified forin of the improvement, and Fig. 9 is a sectional'perspective view of another modified form of the improvement.

Like characters of reference designate corresponding parts in all the views.

As illustrated in Figs. 1, 2 and 3, the metallic tie A is of channel form, and its side members A are bridged or covered by a tie-plate B, on which rests the base of the rail. The tie-plate B is provided at its ends with. downwardly extending lugs B fitting the outer faces of the side members A, of the tie A, and rivets or like fastening devices D are employed for rigidly securing the flanges B to the side members A, so as to securely hold the tie-plate B in position on the tie A, thus strengthening the same and forming an exceedingly strong, durable and comparatively light support for the rails C. The tieplate B is provided with apertures for the passage of fastening lugs E, each having a head E adapted to rest against the under side of the tie-plate B, while the upper end of the lug E is bent over onto the top'of the corresponding flange of the rail 0, as plainly indicated in the drawings. Now the apertures in the tieplate B are arranged in such a manner that two fastening lugs E are used-on each side of the rail, so as to se- Specification of Letters Patent.

i E I curely hold the rail down in position on the tie-plate B. Each lug E is preferebly made of soft steel, so as to permit of its convenieiit bending over onto the flange of the rail, as illustrated in Figs. 1, 2 and 3.

In the modified form illustrated in Figs. 5 and 6, a

fastening lug F is employed resting on the top of .the tie-plate B and secured thereto by a bolt F passing through the tie-plate B. This fastening lugF has its outer portion doubled up to abut with the lower layer against the edge of the flange of the rail 0, while the up- 7 per layer is projected inward, to overlie the top of the flange of the rail 0, thus forming an exceedingly strong and durable fastening means for holding the rail 0 in place on the tie-plate B.

In the modified form illustrated in Fig. 7, the me-' 7 tallic tie A is made of cast steel, and in this case the side members A are integrally connected with each other by a tie-plate A having apertures A for the fastening means, such as above described and shown in Figs. 1 to 6, inclusive.

In the modified form shown in Fig. 8, the channel form of the metallic tie A is approximately U-shaped, with the flanges A extending horizontally for the recepwardly extending flanges B ,'fitting over the outer edges of the flanges A. Rivets or bolts D passing through the tie-plate B and the flanges A serve to securely hold the tie-plate in position on the metallic tie. Suitable tion of the tie-plate B provided at its ends with downfastening lugs G held in place by bolts G on the tieplate B serve to secure the rail 0 in place.

As illustrated in Fig. 9, the tie-plate H is provide with downwardly extending flanges H, fitting against the inside of the vertical members A of the metallic tie A, and the said flanges H are secured by rivets or like fastening devices D to the vertical members A of the tie A. The tie-plate H is provided with apertures H for the fastening devices for holding the rails in place, such as above described and shown in the drawings.

In each of the casesthe fastening means for holding the rails C in place are separate from the tie-plate, but

are connected therewith, so as to: secure the rail in place on the tie-plate, it being, however, understood that each tie-plate has apertures spaced desired distances apart,'

for holding the fastening means in proper relation to the rail to be secured in position on the tie-plate.

In my patent above referred to the rail fastening devices form an integral part of the tie-plates, but by making the fastening devices separate they can be readily removed when broken and replaced by new ones, besides the advantage in the manufacture of the tie-plates without integral fastening devices.

By having the tie-plates span a hollow section a desired flexibility is obtained, to permit the railroad ties to successfully withstand the heavy pounding they receive from the powerful, heavy, high speed locomotives now in use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A tie comprising a channel plate, tie plates crossing the tie near each end thereof and secured to the sides of .the channel plate, said tie plates having pairs of openings therethrough in positions corresponding to the edges of the rail base when in position on the tie plate, and means for securing the rail to the tie plate, comprising lugs adapted to he passed through the openings and having heads for engaging the under face of the tie plate, said lugs being adapted to be bent onto the rail base whereby to secure said base in position.

2. A tie comprising a channel plate, provided with tie plates crossing the tie near each end thereof and secured to the tie, said plates being provided with pairs of openings therethrough, in positions corresponding to the edges of the rail base when in position on the tie, and menus for securing the rail to the tie plate comprising lugs adapted to be passed through the opcnings and having heads for engaging the under face of the tie plate, said lugs being adapted to be bent onto the rail hasc whereby to secure said base in position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses ARCHIE M. BAliil). Witnesses '(,;r:o. W. \YlliGH'l,
